DVD Shrink back-ups are not region-free! Help!

've used and loved this program for a good long while, but realized the other day that I've never tried to back up any of my DVDs from when I was living in England. I tried, it played fine on my PC but on my Sony standalone, I get the message 'playback prohibited by area restrictions.' I tried it on my friend's Toshiba, same thing. And on another one from Radio Shack - these backups will not play on region-protected standalone players!

I tried selecting 'region-free' in DVD Shrink, then someone told me standalones will often play DVDs that are ONLY from that region, so then I tried checking only 'Region 1' - still wouldn't play. Then I tried one with all regions checked, and it still would not play. This really sucks - can someone help me? Otherwise, as much as I hate it, will have to look for other dvd backup solution....
Any help would be greatly appreciated, thanks...!
